BoneSegmentation Mask Channel Mapping
The BoneSegmentation masks are stored as 14-channel .npy arrays with shape:
(14, H, W)
Each channel is a binary mask for one anatomical structure. The official channel order is:
| Channel ID | Anatomy name | Description |
|---|---|---|
| 0 | Capitate | Capitate bone |
| 1 | DistalRadius | Distal radius |
| 2 | DistalUlna | Distal ulna |
| 3 | Hamate | Hamate bone |
| 4 | Lunate | Lunate bone |
| 5 | Tri | Triquetrum / pisiform region |
| 6 | Scaphoid | Scaphoid bone |
| 7 | Trapzium | Trapezium bone |
| 8 | Trapezoid | Trapezoid bone |
| 9 | Metacarpal1st | First metacarpal |
| 10 | Metacarpal2nd | Second metacarpal |
| 11 | Metacarpal3rd | Third metacarpal |
| 12 | Metacarpal4th | Fourth metacarpal |
| 13 | Metacarpal5th | Fifth metacarpal |
The channel semantics are fixed across all samples. If images are canonicalized by hand side, this changes only the image orientation; it does not change the anatomical meaning of the channels.
